  1. Appreciate the knowledge man thanks for the uploads. Have a odd question i think if you dont mind giving me the rundown. Does code allow for the relocation of p traps? In this specific instance, a bath tub, to a section of the drain line remote from being directly beneath the tub to a few feet down the line. (Clearance and consolidation effort). Thank you.

  2. Approx when were S traps abandoned for P traps?
    Which trap is commonly used for basement floor drains?

  3. Another problem with an AAV is that it only handles negative pressure, not positive. If you have something like a macerating toilet or other pump that discharges water at a high rate, the positive pressure could cause bubbling and gurgling in your drains.

  4. Timely. Planning on updating the plumbing, which is all s trapped, no vents. Never had any odor issues tho

  5. I still see them sold right next to p traps and in great quantity. So people must use them somewhere.
